Dyno Results and Track Times LE2.1HL

380RWHP @6250
340RWTQ @4800

93 Firehawk, A4, stock bottom end.
LE2 heads, LE1HL cam, Dyno Tune
JetHot LTs, ORY, 3" Hooker Catback, 3200 Stall

(Results with cutout motor broken, cutout was stuck open about 1/8 )
based on previous tests (this car, this setup), that cost me about about +4rwhp +9rwtq.

Before and after heads/cam/stall/LT (Photoshopped together)

Finally made it to KCIR
My best run was 12.37 @ 110mph with a 1.71 60ft

She was hooking awesome, I later found that my rear shocks were set to 4 instead of 8.
I may have been able to squeeze a little bit more out of it.
I'll know better next time.

Next up, new TC and an oil catch can (Inside of manifold is coated in oil)

KCIR is about 900ft above sea level
It was about 60*, Overcast, 45% humidity.

I'm hoping for 390 or so with a better converter.
Maybe more if cleaning the manifold, installing the catch can and checking the lash on those rockers helps.
We'll find out soon

What brand converter?

Car should be much quicker/faster MPH with 380rwhp.

*edit*.. just saw you're running a ProTorque converter. I'd ditch that and look into a Vigilante or a Yank personally.

As already stated, you should be running a bit quicker and faster with that kind of power. My guess would be somewhere in the mid 11s at around 114-117 depending on weather conditions, vehicle weight and track elevation.

Exactly...

And that is about where I wanted it to be.
A street car that looks good for cruisin', gets me to work every day and
puts down respectable numbers at the track without being gutted.
I run with full interior, leather, power everything, A/C and power steering.
The only changes from street to strip are wheels (DRs/Skinnies) and front swaybar (cuz it's about 35lbs LOL)
And it runs on 91 pump gas.

Let us know how you do when you get the yank in, it should pick up quite a bit. And on the catch can, make sure you don't buy an ebay catch can, you need one with the mesh inside it to condense the vapors into a liquid or it won't end up doing much at all. Thunder racing has a nice one, or if you are on a budget you can do the compressor seperator from lowes or home depot. Oh and what gears are you running?

I agree, I'm not skimping on this project.
I did on the TC and look where it got me.

Running 3.73s

Lol do you know who Pro Torque is? They have more 7 second cars than yank and Vig put together.

Maybe send the converter in to be refreshed?

I'm well aware of who ProTorque is. The last car I know of running a ProTorque (first hand as I was the one that swapped the protorque out of the car for a Vigilante) gained 4 mph ditching it with zero other changes and same conditions at the same track, consistently.

I don't know if it was a bad converter or what (although it was brand new), but it certainly wasn't working well for the combo (cc503 stock head car).

Long-overdue update.

I'm since installed a Yank SS4000 and QA1 drag shocks.
I managed an 11.8@113mph yesterday with a 1.63 60ft. (-100 DA )
My best 60ft was last weekend, when I somehow hit 1.58. (I've since been unable to do any better than 1.60)
She lauches hard and gets both wheels up. (I'll be adding more pics to my cardomain page shortly)
http://i38.photobucket.com/albums/e1...DSC_8737-1.jpg

Not bad at all for a stock weight car with a 275lbs driver.
Should easily pull 11.7s at 115 with a 160lbs guy in the seat ... too bad 230-235 is about as low as I can go with this frame.
I'm gonna have to borrow Skinnies or Tiago as stunt drivers LOL

We tried a few different settings for WOT TCC lockup and ended up disabling it all together.

I've also installed an oil catch can and a 23% UD pully (my stock crank pully was damaged during an opti replacement)
We fixed an exhaust leak in one of my header primaries and modified the Y pipe so it would stop banging my crossmember as well.

That's about it for the season here in KC though.
I'll be back in March for the LTx shootout and the next MOFBODY shootout.
We'll see what fun projects winter brings. (Likely a replacement for the stock 10bolt and a new forged bottom end)

I still DD the car and it runs and handles great.
She'll be parked when it snows though. We get some nasty ice storms in KC
and I really prefer my Firehawks unwrecked LOL
